An assistant superintendent with the Whittier Union High School District said one student was killed and four were injured.

"It is with great sadness that I let you all know that there was a car crash outside the La Serna campus this morning involving an adult driver and five LSHS students,” assistant superintendent Loring Davies said in a statement on the school’s website.

Davies asked students to respond to calls or texts from their parents to confirm their safety.
